I am currently tasked to program an ATtiny404. In order to test the connection I decided to start with an example code that I found in the following guide: Attiny (tinyAVR) series-0 and how to use their GPIO - Daumemo
I have followed the steps as described in the guide on my laptop and personal computer. However, on both machines when I try to build the code it always leads to the following errors:
Verbose mode can be enabled via -v, --verbose option
KeyError: ‘tool-avrdude’:

Could you please help me figure it out? Why the AVRDUDE is failing? I have previously used PlatformIO to program Arduino mega, uno and nano and never had an issue due to a tool during building a code. I do not have much experience programming and could not solve this issue for quite some time.
Thank you for your reply!
I tried deleting all folders that contained AVR in their name in C:\Users\blago.platformio\packages
After which I tried building again which lead to ‘‘toolchain-atmelavr’’ installment and same errors again.

After that I tried installing ‘‘tool-avrdude’’ through the CLI:
PS C:\Users\blago\Documents\PlatformIO\Projects\ATtiny404_HelloWorld> pio pkg install -g -t “tool-avrdude”
Tool Manager: Installing tool-avrdude

Unpacking [####################################] 100%
Tool Manager: tool-avrdude@1.70100.0 has been installed!
Then I tried building the project again which lead to the same errors as the ones shown above. Currently, in ‘‘C:\Users\blago.platformio\packages’’ I have 4 folders only
I do think that you are correct and I have some corrupted files. However, I am not sure how to completely remove AVRDUDE and reinstall it. Additionally, it is strange that I get these exact same errors on two different PCs.
Please close VSCode,delete the whole C:\Users\blago\.platformio folder, then reopen VSCode. The PlatformIO extension will redownload the core and you try and build and upload your project again.
I just deleted the ‘’.platformio’’ folder and tried building the project again. Unfortunately, I still get the same errors. Additionally, a colleague of mine who works as embedded system engineer told me that I may have issues with python on my PC which I also reinstalled and checked if it is installed correctly and has a proper path in system environmental variables which I believe it does. That did not help either.
Hmmm this might actually be a PlatformIO bug. The platform.json’s package declaration says
which is the tool-avrdude-megaavr package, not the tool-avrdude package. Yet the main.py references
You might be able to work-around this bug by creating a Board: Arduino Uno + Framework: Aruduino project with empty code first, upload that so that it triggers the installatin of tool-avrdude, then switch to your atmelmegaavr project again.
